Inscription. From this vantage point it is possible to see the principal elements of Ft. Warren’s defense system. These are based on the 17th century, military theories developed by Louis XIV’s chief engineer, Sebastien de Vauban, and were modified to meet 19th century requirement. In theory, and attacking ship would be pounded by heavy fire from the ramparts. The fort’s earthen coverface and escarpments would absorb enemy fire from the channel. Any landing party would be raked by fire from outworks such as the coverface. If the enemy reached the moat they would be caught in a crossfire between cannon mounted in the flak walls of the bastions and rifle fire from the curtain wall.

Welcome to Fort Warren-It was built more than 150 years ago-a fort on an island, a key to the coastal defense of a new nation. It was transformed into a prison during the Civil War, housing hundreds of Confederates within its granite walls, ordinary soldiers and high level politicians alike. It served our nation for more than 85 year as a vigilant sentinel in the harbor. It made over into a park is an extraordinary island setting. Welcome to Fort Warren, on Georges Island. Welcome to the Boston Harbor Islands National Recreation Area.
